  • 6Servings


  • Salt and pepper
  • 1/2 pound carrots, sliced 1 inch thick
  • 1/2 pound celery root bulb--trimmed, peeled and cut into 1-inch cubes--or 1/2 pound parsnips, peeled and sliced
  • 1 pound whole grain or whole wheat elbow macaroni or other small-cut pasta
  • 4 tablespoons butter
  • 1 small onion, finely chopped
  • 2 large cloves garlic, finely chopped
  • 3 tablespoons flour
  • 2 cups whole milk
  • 1 tablespoon Old Bay Seasoning
  • 2 1/2 cups grated sharp yellow cheddar cheese (about 9 ounces)
  • 1/2 cup pickled vegetables or giardiniera salad, drained and finely chopped


Bring a pot of water to a boil, salt it, add the carrots and celery root (or parsnips) and cook until tender, about 10 minutes. Drain, then transfer to a food processor and puree.

Meanwhile, bring a second large pot of water to a boil, salt it, add the pasta and cook until 2 minutes shy of al dente. Drain and return to the pot.

While the pasta is working, in a large saucepan, melt the butter over medium heat. Add the onion and garlic and cook for a few minutes, then whisk in the flour. Whisk in the milk and simmer until thickened, about 3 minutes. Season with salt, pepper and the Old Bay. Add in 2 cups cheddar to melt, stirring in a figure-eight motion with a wooden spoon.

Preheat the broiler. Stir the pureed vegetables and cheese sauce into the pasta. Transfer to a casserole dish and top with the remaining 1/2 cup cheddar. Broil until bubbly and brown, about 5 minutes. To serve, top with the pickled vegetables.
